When bits TPSC2 to TPSC0 in TCR4 are set to B'000 and ø/1 is used as the
TCNT4 count clock, this setting is invalid and input capture is not generated.
When the BFB bit in TMDR3 is set to 1 and TGR3D is used as a buffer register,
this setting is invalid and input capture/output compare is not generated.
